Serotonin is a neurotransmitter that can improve mood, enhance sleep and reduce the sensation of pain.
According to researchers, folic acid deficiency can lead to decreased levels of serotonin in the brain. Folic acid, also known as vitamin B9, helps to prevent neural tube defects during fetal development and can also protect the body against heart disease and some types of cancers.
Fruits and vegetables that contain folic acid can help to boost serotonin levels and improve mood. Some examples are spinach,broccoli, papaya,oranges,grapefruit,strawberries,okra (bhindi),green peas,peanuts,almonds, corn,carrots and squash etc.
Dairy products can contribute to increase in serotonin because they contain a simple sugar called lactose. Simple sugars help boost serotonin levels, which can help improve mood or make it easier to fall asleep.
Carbohydrate consumption can also improve serotonin levels. Because serotonin can decrease the perception of pain, improve mood and induce sleep, some people may unconsciously crave high-carbohydrate foods when they need to relax or rest.
